Director: Natalie Portman did 80% of Black Swan dancing

Black Swan director Darren Aronofsky has come out in defence of Natalie Portman after her dance double in the
film, Sarah Lane, claimed the actress only did five percent of the
full body shots in the film. "I had my editor count. There are 139
dance shots in the film. 111 are Natalie untouched. 28 are her
dance double Sarah Lane," he said in a statement. "If you do
the math that's 80% Natalie Portman. There are two complicated
longer dance sequences that we used face replacement. Even so, if
we were judging by time over 90% would be Natalie."

The director praised the Oscar winner's dedication to the role,
saying: "I am responding to put this to rest and to defend my
actor. Natalie sweated long and hard to deliver a great physical
and emotional performance."

Sarah Lane, who was credited as stunt double, claims this wasn't
the case: "They wanted to create this idea that Natalie was some
kind of prodigy and worked so hard to make herself a ballerina in a
year and a half, basically because of the Oscar," said Lane. "It is
demeaning to the profession and not just to me."
